Since the mounting holes 31 are formed through both ends of the connection ring 30, the connection pipe 20 is mounted in the connection ring 30 to be communicated with the inner cavity 11.
Specifically, the connection ring 30 has a substantially circular ring-shaped structure, the connection ring 30 is sleeved inside the connection pipe 20, and the connection ring 30 is hermetically connected to the housing 10 outside the connection ring. So just formed the assembly between takeover 20, clamping ring 30 and the casing 10 three, the mode of takeover 20 with casing 10 lug connection has been changed in addding of clamping ring 30, has reduced the degree of difficulty of processing, has strengthened the quality of connecting, welding operation is simple, and welding performance guarantees easily, also realizes automated production easily, has reduced the adverse effect of vibration to reservoir 100, has prolonged the life of reservoir 100.
Further, the end of the adapter 20 close to the housing 10 is provided with a flared section 21. And the flared section 21 extends into the mounting hole 31 to be connected with the connecting ring 30.
It should be noted that, the arrangement of the connecting pipe 20 near the flared section 21 at one end of the housing 10 increases the diameter of the connecting pipe 20, so that the connecting pipe 20 and the connecting ring 30 are in interference fit, and the connection strength between the connecting pipe 20 and the connecting ring 30 is enhanced.

That is, the ratio H of the height of the mounting hole 31 to the depth of the adapter 20 extending into the mounting hole 312/H3May be 60%, 70%, 80%, 90% or any ratio within this range.
It should be noted that the ratio H of the height of the mounting hole 31 to the depth of the adapter 20 extending into the mounting hole 312/H3In fact, the insertion rate of the adapter tube 20 into the mounting hole 31 directly affects the connection strength between the adapter tube 20 and the connection ring 30. The adapter 20 can be inserted neither too deeply nor too shallowly into the coupling ring 30. Too deep may cause structural breakage between the adapter tube 20 and the coupling ring 30, and too shallow may cause too low a contact area between the adapter tube 20 and the coupling ring 30, resulting in weak welding therebetween. Therefore, the content of the active carbon is 60 percent≤H2/H3Less than or equal to 90 percent, thereby ensuring the connection firmness between the connecting pipe 20 and the mounting hole 31, if H2/H3Over 90%, the interior of the reservoir 100 may be affected.
As shown in fig. 3, the guide structure 32 includes a chamfer 321. The two ends of the chamfer 321 are respectively connected with the hole wall of the mounting hole 31 and the end surface of the connecting ring 30 facing the inner cavity 11. The vertical distance from any point on the chamfer 321 to the central axis of the connecting ring 30 decreases gradually from the adapter 20 towards the inner cavity 11.
It should be noted that, the vertical distance from any point on the chamfer 321 to the central axis of the connecting ring 30 gradually decreases from the connecting tube 20 toward the housing 10; that is, the chamfer 321 is disposed obliquely, and the chamfer 321 is disposed away from the end of the inner cavity 11 and is flared, and the chamfer 321 is disposed close to the end of the inner cavity 11 and is tapered. Because the connecting pipe 20 and the connecting ring 30 are connected together in a welding manner by the welding material, in order to ensure that the welding material can smoothly flow into the gap between the connecting pipe 20 and the mounting hole 31, the chamfer 321 is set in the inclined manner, when the connecting pipe 20 is matched and assembled with the mounting hole 31, the chamfer 321 not only can lead the welding material to be guided by the chamfer 321 and smoothly flow into the gap between the connecting pipe 20 and the mounting hole 31, and the welding strength between the connecting pipe 20 and the connecting ring 30 is improved; and moreover, the connecting pipe 20 can be guided to be smoothly inserted into the mounting hole 31, so that the operation difficulty in mounting is reduced, and the assembly effect is improved.
Further, the included angle between the chamfer 321 and the central axis of the connecting ring 30 is α, and α satisfies the relation: alpha is more than or equal to 20 degrees and less than or equal to 60 degrees. That is, the included angle α may be 20 °, 30 °, 40 °, 50 °, 60 °, or any value within this range.
It should be noted that if the included angle α is too small, the guiding function of the chamfer 321 is weakened, so that the chamfer 321 does not have the effect of guiding the assembly of the solder and the guiding adapter 20; if the included angle α is too large, the solder cannot flow into the gap between the adapter 20 and the mounting hole 31, and the chamfer 321 cannot conduct the flow.
Further, the height of the chamfer 321 is H along the central axis of the connecting ring 301And H is1Satisfy the requirement ofThe relation is as follows: h is not more than 0.2mm1Is less than or equal to 1 mm. That is, the height H of the chamfer 3211And may be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, or any value within this range.
The height H of the chamfer 3211Neither too low nor too high. Such as height H1Too low, the guiding effect of the chamfer 321 is reduced, so that the chamfer 321 does not have the effect of guiding the assembly of the solder and the guiding adapter 20; such as height H1Too high may reduce the contact area between the mounting hole 31 and the adapter 20, thereby affecting the contact height between the mounting hole 31 and the adapter 20, and further affecting the welding firmness of the adapter 20 and the connection ring 30.
Before the adapter tube 20 is mounted on the housing 10, the connecting ring 30 is firstly inserted into the first opening 12 to be welded with the housing 10, then the adapter tube 20 is inserted into the mounting hole 31 from the chamfer 321, the inclined arrangement of the chamfer 321 guides the adapter tube 20 to be inserted into the mounting hole 31, and then the solder is guided to the gap between the adapter tube 20 and the mounting hole 31 through the chamfer 321, so that the welding between the adapter tube 20 and the connecting ring 30 is realized.
The present invention also provides an air conditioning system (not shown), including the above liquid reservoir 100.
